Apocalypse Rules: Others flee in heavy trucks, I crash into leviathans with a toy car!

What the story is about

After an apocalypse transports humanity to a world of deadly rule distortions, Suin awakens the Infinite Devour system, which lets him consume objects for energy and upgrade himself and his exclusive vehicle—a coin-operated kitty ride. As he travels toward a safe zone, he clashes with ruthless survivor groups, encounters powerful monsters, and gradually builds a small team of allies.
